Some of Donald Trump’s surrogates in Arizona are sounding the alarm about an Arizona GOP directive that they say may hurt the tycoon in his battle with Ted Cruz for delegates to the Republican National Convention.

DeWit agrees with a growing sentiment among some activists that the Arizona Republican Party’s requirement that district and county parties allow proxy votes in selecting state convention delegates hurts Trump and aids Cruz.

Some longtime Republican activists are speculating that the Arizona Republican Party’s decision to allow the use of proxy votes at the 40 district and county meetings (where 1,251 delegates to the party’s April 30 state convention were elected) is not only a break from decades of precedent, but potentially a strategy to undermine Trump.
